YACHT-RUBBER.

SPECIFICATION forming part Of Letters Patent N O.' 71 5,176, dated.December 2, 1902;

Application filed April 4, 1902. Serial No. 101,325. (No model.)

To all whom it may concern:

Be it known thatl, GEORGE W. SWAN,acitizen of the United States,residing at Toledo, in the county of Lucas andS tate of Ohio, haveinvented certain new and useful Improvements in Yacht-Rudders; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit ap pertains to make and use the same.

My invention has reference to a rudder for sail-yachts, and has for itsobject to provide a rudder the blade of which will at all timestake aposition near the vertical plane.

In carrying out my invention I provide means whereby the rudder-blade isturned upon the rudder-post as an axis, and the same is also turned uponan axis at an angle to the axis ofthe rudder-post. l

. It consists in the novel arrangement hereinafter shown, described, andclaimed.

In the drawings, Figure 1 is a side elevation showing my improved rudderas applied to the hull of a yacht. Fig. 2 is an elevation of the sternof a yacht to further disclose my invention.

Referring to the parts, 1 indicates the hull of a yacht, and 2 therudder-post passing upward through the hull in the ordinary manner.- Thelower end of the rudder-post is pivotally supported at 3, and 4 is anordinary tiller for turning the rudder-post.

5 indicates the rudder-blade, pivotally mounted at the lower end of therudder-post, so as to turn upon an axis atan angle'to the axis of therudder-post; Any suitable means may be employed for pivotally mountingthe rudder-blade. In the means shown the inner end of the rudder-bladeis in the form eta casting 6, havinga central perforation to. re-

ceive a bolt 7, secured in the lower end of the rudder-post, upon whichthe blade turns.

' The upper end of the casting 6 is providedv with a segmental gear 8,adapted to engage a segment of a gear 9, rigidly secured to the hull ofthe yacht, and the same immediately. adjoins the rudder-post. It will beapparent that as the rudder-blade is turned upon the rud'derpost as anaxis the same will also be turned upon an axis at an angle thereto. Thisarrangement will maintainthe rudderblade in or near the vertical plane,even though the yacht is sailing on her beam.

This is readily apparent when it is remenh bored that the rudder-bladeis made to assume a position toward the low side of the yacht insailing. The turning of the rudder-post will cause the rudder-blade toalso turn upon its axis at an angle to the axis of the rudder'post toassume a position in dotted lines a, Fig. 2, or a position in proximitythereto. In this figure the altered position of the hull when leaning isshown by the water-line m as, the water-line when the yacht is on aneven keel being indicated by the line y. j

From the foregoing the advantages and utility of my invention will beapparent.

Having described my invention, what I claim, and desire to secure byLetters Patent of the United States, is

1. In a rudder, the combination withthe rudder-post, of a rudder-bladepivoted thereto at an angle to the axis thereof, and means forturning'the rudder-blade upon its angular axis simultaneously with theturning of the rudder-post.

2. A rudder for sail-yachts comprising a rudder-post, a rudder-bladepivoted at the lower end of the post, a segmental gear upon theblade,and a segmental gear secured upon the hull of the yacht adapted toengage the gear upon the blade, as shown and for the purpose set forth.

In testimony vwhereof I hereunto affix my signature in presence of twowitnesses.

GEORGE W. SWAN.
